Efectos de tratamientos térmicos post-alcalinos sobre las propiedades superficiales de titanio para implantes dentales con diferentes recubrimientos

Abstract: RESUMEN El titanio es ampliamente utilizado como implante dental dado que es bioinerte y osteointegrable. Sin embargo, dado que este material no puede inducir el crecimiento de hueso desde su superficie, es usual que se le realicen distintos tratamientos superficiales para desarrollar recubrimientos bioactivos. El tratamiento alcalino tiene por objetivo formar un gel de titanato de sodio amorfo, el cual se puede estabilizar, por medio de un tratamiento térmico posterior. Durante este último, el hidrogel se des… Show more

“…This result must be related to the amorphous nature of the products formed during the reaction of titanium with peroxide and the nanometric thickness of the layer [44]. During the thermochemical treatment, the amorphous structure of the AEAT surface was transformed into crystalline titanium dioxide (anatase variety) [45][46][47]. In the diffraction patterns of the AEPTTT surface (Figure 7C), two peaks of low intensity were observed on 25.1º and 36.5º, corresponding to reflection 101 and 004 of the anatase.…”
